Thank you man. Just got a amazing gift from my dad, a 8" Dobsonian. I had idea how to properly work it until now.

It's really simple, after you figure it out. After you assemble and align things, you just aim it, look, and focus, then swap-in a higher ocular. Don't forget to let the mirror equalize in temperature slowly and thoroughly. Don't forget to get yourself a RED flashlight (there are phone apps) so you can see/adjust things in the dark, unless you set up before sunset, then have a few beers while it gets dark. ;) BTDT

I was going to comment on this last night and got side tracked. We need more videos like this so beginners can see the working ends of how a telescope like this works. Great Video and very informative. Astronomy is the most amazing thing and with today's technology and the more advanced scopes with larger mirror cells or glass; the heavens are limitless.

I think it would be a god idea to start with a 4-inch or 6-inch Dob telescope, instead of this big thing in the video. This guy is definitely not a beginner.

@@toml.8210 I put an 8 in Dob OTA on a CG-4 equatorial mount, going to work just fine and you can do real and fine adjustments to track or install a tracking motor. You touch it, the shake is under 1 second. I have my 10 in Dob OTA rigged to put on it and the extra counterweights, tried it indoors, and waiting for a storm to clear out to take it outside. The key for 10 in is your height and weight. For the CG-4, I am going to use a hex wrench to turn up more tension to the two clutches for slewing it around. This is built into the CG-4. You have to be tall to hoist up the 10 in and you install it with one thigh as a brace for the bottom until it is clamped in. A Dob mount is useful for storage, I am not aware of any other good use, and using one for actual observing probably leads to a lot of people giving up astronomy. I have a 5.2 in Newtonian. This is trivial to handle and is on a much lighter equatorial mount.

Pleased to see that you pointed out it is A Newtonian reflector telescope invented by Sir Issac Newton about 400 years ago, sitting on a basic alt/az mount attributed to John Dobson 400 plus years later. So many newcomers are under the impression that John Dobson invented this optical system. Always nice to help get accurate information out there. Good viewing. 🔭🇦🇺

All Mr. Dobson really did was to find a better bearing system, using Teflon pads in stead of ball bearings, and the stable base box. Ball bearings are terrible for large telescopes.

Still, I found it to be very interesting and impressive watching Dobson building an entire telescope from scratch. Particularly the way he shaped the mirror by hand. I feel he deserves some credit for the part he played in making these amazing instruments somewhat more accessible to us.

Thank you for your informative videos!! I recently bought myself a Skywatcher Flextube 200p - 8" Dobsonian with the Synscan. Got it for a great price on sale $699. I have a question about collumating it...if you can help me . I have a good laser collumator and it definitely shows off target.. . it's in need of collumation..... So I'm looking at the Rear of the OTA and there are only three small Phillip's head screws which are very tight.....they appear to be holding on the outer trim ring of the OTA rather than for collumation. How do I collumate the Primary mirror on the OTA then ?? Did Skywatcher somehow seal the parabolic Primary mirror requiring collumation at the secondary mirror only??? I DON'T want to start messing with screws as I'm afraid to strip them . Any help is greatly appreciated.

@@DrayG42 very small white plastic wheels, about 2 or 3 (one inch) centimeters in diameter and 1 centimeter (half an inch) wide, whose axle is supported by a small metal bar that ends at each end in one of the two branches. or arms from a piece of metal similar to an inverted U. They are wheels that do not turn right left but can only go forward and backward. Placed on the periphery of the platform on which the telescope is located so that they occupy one of the 4 points that are formed every 90º in the circle that forms the base of the platform: there only the wheels can go forward and backward, but on the direction in which they are placed, they only allow the platform to rotate around the virtual axis of the telescope block and its base. In the Dobson, it allows the telescope block to be rotated in the azimuth direction with extremely small displacements and with enormous smoothness and with just minimal pressure from my hand. Of course, a motorized Dobson is better

Although this is really classic Dobson mount, it looks like it should work. the actual Dobson mount relies on Teflon bearings, a large-diameter Altitude bearing ring, and the weight&balance of the OTA to keep it from moving without having to "lock" the alt bearing. Mine needs only a slight finger pressure to slew the tube. It's too bad you can't add digital slewing gear to the tube, to simplify photography.
